and maintenance.
2. Safety
• Before installation or maintenance, ensure the mains supply to the PIR sensor
is switched off and the circuit supply fuses are removed or the circuit breaker
turned off.
• It is recommended that a qualified electrician is consulted or used for
the installation of this PIR sensor and install in accordance with the
current IEE wiring and Building Regulations.
• Check that the total load on the circuit including when this PIR sensor
is fitted does not exceed the rating of the circuit cable, fuse or circuit breaker.

4. Selecting a Location
• The motion detector has number of detection zones, at various vertical
and horizontal angles as shown (see diagram “A”).
• The best all-round coverage is achieved with the unit mounted
at the optimum height of 2.5 metres.
• Careful positioning of the sensor will be required to ensure optimum
performance (see diagram “A” & “B” detailing detection range and direction).
• The sensor is more sensitive to movement ACROSS its field of vision than to
movement directly TOWARDS (see diagram “B”). Therefore position the unit
so that the sensor looks ACROSS the likely approach path.
• Avoid positioning the sensor where there are any sources of heat in the
detection area (extractor fans, tumble dryer exhausts etc.) including opposite
any other light sources such as other security lights.
• Reflective surfaces (i.e. pools of water or white painted walls) may cause
false activation under extreme conditions.

7. Operation and Testing
Walk Test Procedure
• The adjustment knobs located beneath the sensor head (see diagram “G”)
are factory set to “Walk Test Mode” i.e. LUX set to the ‘Sun’ symbol
and the Time set to the minimum.
• Turn the power to the unit ON. The lamp will illuminate for approximately
30 seconds. This indicates the unit is wired correctly and the unit
is in Test Mode.
• Adjust the sensor head to the desired direction for best coverage
(See diagram “B”).
Test Mode – Three LED’s Visible
• The lamp will now illuminate for approximately 2 seconds every time
movement is detected.
• Walk across the detection area approximately 5 metres from the unit.
Each time you are detected the lamp will illuminate. Now stand still until
the lamp extinguishes (this should take approx. 2 seconds)
• Start moving again, when you are detected again the lamp will illuminate.
• Repeat the above, walking at various angles and distances to the unit.
This will help you to establish the detection pattern.
• If the detection area is too small for your requirements, try angling
the sensor head up.
• Angling the head downwards will reduce the detection area should
a smaller range be required.

Setting Up For Automatic Operation –
3 scrolling LED’s Visible
• After walk tests are complete, simply cease movement within the detection area
for approximately 60 seconds the unit will switch into Automatic Mode, this is
indicated by the illumination of three scrolling LED’s in the top transparent
area of the sensor head. These LED’s will scroll from left to right during
daylight and darkness.
• The TIME setting controls how long the unit remains illuminated following
activation, and after all motion ceases (See diagram “G”. the time adjustment
knob is indicated by the ‘Clock’ symbol).
• The minimum time (fully anti-clockwise) is approx. 5 seconds, whilst the
maximum time (fully clockwise) is approx. 18 minutes. Set the control to the
desired setting between these limits.
• The DUSK control determines the level of darkness required for the unit
to start operating. The setting is best achieved by the procedure below
(See diagram “G”. the Dusk adjustment knob is indicated by the ‘Moon’
and ‘Sun’ symbols);
1. Set the DUSK control knob fully anti clockwise.
2. When the ambient light level reaches the level of darkness at which you wish
the lamp to become operative (i.e. at dusk) SLOWLY rotate the control in a
clockwise direction until a point is reached where the lamp illuminates.
3. Leave the control set at this point.
• At this position the unit should become operative at approximately the same
level of darkness each evening.
• Observe the operation of the unit. If the unit is starting to operate too early
(i.e. when it is quite light) adjust the control slightly anti-clockwise.
If the unit starts to operate too late (i.e. when it is very dark).
Adjust the control slightly clockwise.
• Continue to adjust until the unit operates as desired.
• The LED’s will scroll from left to right, day and night; indicating the unit
is in Automatic Mode. The LED’s will extinguish when the PIR activates
the light for as long as the lamp is illuminated.

Masking the Sensor Lens
• To restrict the sensor coverage, preventing detection in unwanted areas, mask
the sensor lens using the masks provided in the accessory pack (see diagram H).
• The top section of the lens covers long range detection, the bottom covers short
range. Similarly the left and right lens sections cover the left and right detection
areas respectively.
Manual Override Mode – Single LED Illuminated
The light can be switched on for longer time periods by use of the Manual
Override Mode. This can be activated at night by using the internal wall switch
or circuit breaker.
• Switch the internal wall switch/circuit breaker twice (OFF/ON, OFF/ON)
within 2 seconds.
• The unit will now illuminate continuously for the user defined time,
between 1 – 8 hours, or until the unit is switched back into auto mode.
• The ON time can be set by rotating the centre adjustment knob as required
(see diagram G). This time adjustment is factory set to 1 hour
(Fully anti-clockwise is 1 hour, fully clockwise is 8 hours).
Note: If the light is still ON at dawn, before the set time expires, it will
automatically switch OFF.
• The Manual Override Mode can be setup in the day time or at night time.
• In the day time, the Manual Override mode is indicated by the permanent
illumination of a single red LED in the top of the sensor head.
• At night time, no red LED will be visible.
• To switch the unit back into Auto Mode, flick the internal wall switch/circuit
breaker (OFF/ON) once within 1 second. The unit will return to Auto Mode.
This is indicated by the return of the left to right scrolling LED’s as described
in Automatic Operation above.
Holiday Mode – Single LED Flashing
The benefit of Holiday Mode is that the user can program the unit automatically
illuminate for a certain time, (1 – 8 hours) each night. At dusk the unit will
illuminate for this set period after which it will extinguish. The unit will continue
to operate normally when it senses movement until dawn. At dusk the following

11. Troubleshooting
Problem
• Lamp stays ON
all the time
night and day.
Solution
The unit may be suffering from false activation.
Cover the sensor lens completely with a thick cloth.
This will prevent the sensor from “seeing” anything.
If the unit now switches off after the set time duration
and does not re-activate, this indicates that the
problem was caused by false activation. The problem
may be solved by slightly adjusting the direction/angle
of the sensor head (see previous section).
Check LED status:- If a single LED is constantly visible,
the unit is in Manual Override Mode and will illuminate
until dawn or until reset to Automatic Mode. To reset
to Automatic Mode, switch the internal switch/circuit
night the process will be repeated, the unit will remain on for this set period
(0 – 8 hours) and then will operate as a PIR unit until dawn.
• Switch the internal wall switch/circuit breaker 3 times (off/on off/on off/on)
within 2 seconds. A single flashing red LED at the top of the sensor head
indicates Holiday Mode.
• The unit will now illuminate for a user defined time between 1 and 8 hours.
The time can be set by rotating the centre adjustment knob as required.
(See diagram G, the adjustment knob is identified by the letter T inside a circle.)
• This time adjustment is factory set to 1 hour.
Note: Fully anti-clockwise is 1 hour, fully clockwise is 8 hours.
• After the defined period has elapsed, the unit will return to Automatic Mode
and operate as previously set up and the three scrolling LED’s will illuminate
from left to right.
• Holiday Mode will NOT reset to Automatic Mode at dawn, it will repeat each
night until reset by the user.
• To cancel Holiday Mode, switch the internal wall switch/circuit breaker once
(OFF/ON) within one second. The unit will turn to Automatic Mode indicated
by the scrolling LEDs.

breaker off/on within one second. Automatic Mode is
indicated by scrolling LEDs from Left to right. If a single
flashing LED is visible, Holiday Mode has been selected.
Switch the internal wall switch/circuit breaker OFF/ON
with one second and the unit will return to Automatic
Mode. The light will illuminate only when motion is
detected. Automatic Mode is indicated by scrolling
LEDs from Left to right.
You may not be allowing the unit time to complete
its warm-up period. Stand well out of the detection
range & wait (the warm-up period should never exceed
5 minutes). Occasionally, wind may activate the PIR.
Also passages between buildings etc. can cause a
‘wind tunnel’ effect. Ensure the unit is not positioned
so as to allow detection of cars/people using public
thoroughfares adjacent to your property.
Check that the power is switched ON at the circuit
breaker/internal wall switch. Turn OFF the power to
the unit & check the wiring connections (See section 6.
Connection Diagram). Ensure no connections are loose.
Check the lamp. If the lamp has failed, replace. Ensure
that the lamp is seated correctly in the lamp holder.
The level of ambient light in the area may be too bright
to allow operation at the current DUSK setting.
During the hours of darkness, adjust the DUSK control
slowly clockwise until the lamp illuminates.
Refer to previous section for more details.
